Non-denominational evangelical churches universally affirm that the Holy Spirit is the third person of the Trinity who indwells believers, convicts of sin, produces sanctification, and empowers the church. However, there is significant variation within the movement regarding the nature and extent of the Spirit's gifts.

Some non-denominational evangelical churches are explicitly cessationist, holding that miraculous gifts (tongues, prophecy, healing) ceased with the apostolic era. Others are fully charismatic or Pentecostal in practice, including speaking in tongues, prophecy, and words of knowledge. The large majority fall somewhere in between — affirming the Spirit's ongoing work in general while being cautious or selective about specific charismatic manifestations. This spectrum makes the non-denominational evangelical world one of the most internally diverse contexts on the question of spiritual gifts.

Many of the largest and most influential non-denominational evangelical churches (e.g., Willow Creek, Saddleback, North Point Community) have deliberately avoided positioning themselves at either extreme of the cessationist-charismatic spectrum, creating broad-tent communities that welcome people from various backgrounds on this secondary question.
